  1. Module 9: SQL Server 2005 Replication

  2. Overview • Overview of Replication Enhancements • New Types of Replication • Configuring Replication

  3. Lesson: Overview of Replication Enhancements • User Interface Enhancements • Replication Management • Performance and Scalability • Replication Monitor • Other Enhancements

  4. User Interface Enhancements • Replication wizards • 40% fewer pages • Improved default values and auto-detection • Less branching • New Subscription Wizard • Replaces the Push Subscription Wizard and Pull Subscription Wizard • Allows you to define multiple subscriptions with different properties at the same time

  5. Replication Management • Initializing a subscriber • Backup and restore • Copying a database • Dynamic snapshots • Resuming snapshot transfers • Replicating DDL statements • Allowing anonymous subscriptions for all publications

  6. Performance and Scalability • Precomputed partitions • Updates to unique keys • Transactional parallelism — independent agent option used by default • Download only articles — to reduce change tracking metadata • Reduced contention on reporting subscribers • Use snapshot isolation level • Use snapshots

  7. Replication Monitor • Independent from SQL Server Management Studio • Passive monitoring • Define acceptable performance figures • Minimize monitoring impact • Merge replication • Article level statistics • Upload and download statistics • Transactional replication — real-time monitoring with tracer tokens

  8. Other Enhancements • Merge replication concurrency enhancements — guaranteed delivery of logical records • Programming changes — release of RMO • Replication of more types of objects • .NET UDTs • Assemblies

  9. Lesson: New Types of Replication • Heterogeneous Replication • Peer-to-Peer Transactional Replication • HTTP Replication

  10. Heterogeneous Replication • Use Oracle v8 and later databases as the publisher in a replication system • Snapshot replication — no impact on Oracle database • Transactional replication • Triggers and tracking tables added to Oracle database • Log Reader Agent transfers changes to SQL Server Distributor and Distribution Agent transfers changes to subscribers • Potential issues because of: • Differences between SQL Server and Oracle • Use of Oracle tools

  11. New York New York Distribution Agent Distribution Agent Log Reader Agent Log Reader Agent Peer-to-Peer Transactional Replication London Sydney Distribution Agent Log Reader Agent Distribution Agent Log Reader Agent

  12. HTTP Replication Binary over TCP/IP XML over HTTP/HTTPS Subscriber Firewall IIS Publisher https://Repl.AdventureWorks.com

  13. Lesson: Configuring Replication • How to Configure Replication Using SQL Server Management Studio • How to Configure Replication Using RMO

  14. How to Configure Replication Using SQL Server Management Studio • Creating a publication — New Publication Wizard • Creating a subscription — New Subscription Wizard • Synchronizing a subscription

  15. Practice: Creating a Publication Using SQL Server Management Studio In this practice, you will see how to: • Start the New Publication Wizard • Configure a publication

  16. How to Configure Replication Using RMO 1 Reference the SMO and RMO libraries • Microsoft.SqlServer.ConnectionInfo • Microsoft.SqlServer.Replication Import the SMO and RMO namespaces Connect to the replications server(s) Perform replication tasks • Create publications • Create subscriptions 2 3 4 Imports Microsoft.SqlServer.Management.Common Imports Microsoft.SqlServer.Replication Dim subCon As ServerConnection subCon = New ServerConnection("MySubscriber") subCon.Connect()

  17. Practice: Creating a Subscription Using RMO In this practice, you will see how to create a subscription using RMO

  18. Course Evaluation
